checking unused days on park hoppers

[crzy4mk]

If I have park hopper passes that I think have unused days, but I'm not sure, can I have them checked somewhere other than WDW? Like a Disney store maybe?

According to allearsnet.com:

"The only way that you can find out what is left on old tickets is in person at WDW. Any resort front desk, Guest Services, or Guest Relations window can scan them and tell you what remians unused on them. The Disney Stores cannot tell you nor can you find out over the telephone."
